WRT54GS wireless stoped working

Hello i have an old WRT54GS v1.1 , which was working fine , but today i switched wireless back on and the light come on to say Wlan is on , but the psp's, Phone and laptop all say there's no wireless signal , i'm using Tomato 1.17 , i've reflashed the image , cleared NVRAM , downgraded the firmware to 1.15 , but still nothing .
Is it possible that the routers had it ?? or is there something i could try to get it back working again ???

Ok i've put the latest official firmware on from linksys , but it's still the same , it shows that wireless is on , the wlan lights on and in the config it's on , but nothing picks up a wireless signal ...
